PLEASE READ ALL OF THE INFORMATION BELOW PRIOR TO INSTALLATION.

This image shows where the foot pedal’s free play comes from. Some clearance is absolutely necessary; otherwise, the seals may be pushed forward enough to prevent the intake/return ports from opening up again, allowing excess pressure to vent to the reservoir.

  1. SWAP THE FLUID SENSOR CONNECTOR, IF NECESSARY
    Inspect the new unit, making sure the brake master fluid sensor is on the correct side. As many of our units are suited to both left-hand and right-hand drive vehicles, in most cases, the sensor can be easily removed and swapped to the opposite side.
  2. ADJUST THE BRAKE BOOSTER PUSH ROD CLEARANCE
    Mount the brake master onto the brake booster and check to see if you have the correct clearance. We recommend aiming for a brake booster push rod clearance of 0.5 – 1.0mm. While this can be done by trial and error, there are specific tools to this task that can make this adjustment faster, easier and more precise. See our Brake Booster Push Rod Adjusting Tool. Remember; nothing you do at the pedal affects clearances inside the master cylinder body until the push rod starts to push the seal assemblies forward. If there is too much clearance, the pedal will feel soft and have excessive travel.
  3. BENCH BLEEDING
    Remove the brake master and bench bleed it to remove any air from the unit, making the final system bleed much quicker.
  4. FINAL INSTALLATION AND SYSTEM BLEEDING
    Install the brake master and bleed the brakes in the following sequence: LHR, RHR, LHF and RHF.

NOTES:
*Modifying vehicles is a specialist task and requires the knowledge and experience of competent individuals to be conducted safely. We recommend this product be installed by a competent person. 

**Please ensure the Brake Master (Brake Lines, Proportioning Biased Screw and Reservoir Grommets etc.) is free from fault or leaks immediately after installation, as we will not be liable for damages.
